FREDERICK C. BOYNTON, OF SPBINGPARK, MINNESOTA, ASSIGNOR OF ONE-HALF TOERNEST R. GAYLORD, OF MINNEAPOLIS, MINNESOTA.

COMBINED SCRAPER AND RAKE.

Application filed June 11, 1914.

To all whom it may concern Be it known that I, FREDERICK C. BoYN- TON, acitizen of the United States, residing at Springpark, in the county ofHennepin and State of Minnesota, have invented certain new and usefulImprovements in a Combined Scraper and Bake; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention has for its object to provide a simple and eflicientscraper attachment or device for rakes.

In the preferred arrangement, a scraper attachment is provided with adevice for cleaning or loosening the grass and leaves from the raketeeth, so that the said attachment, in its preferred form, is in thenature of a combined scraper and cleaner. The complete device is in thenature of a combined scraper and rake.

Generally stated, the invention consists of the novel devicesand'combinations of devices hereinafter described and defined in theclaims.

The attachment is especially adapted for use in raking up acorns, leavesand short cut grass which would pass between the teeth of an ordinarylawn or garden rake.

In the accompanying drawings which illustrate the invention, likecharacters indicate like parts throughout the several views.

Referring to the drawings: Figure 1 is a view partly in side elevationand partly in section showing the combined scraper and rake, some partsbeing broken away; Fig. 2 is a view corresponding to Fig. 1, butillustrating a different position of the scraper blade; Fig. 3 shows thecombined rake and scraper in plan view with some parts broken away andwith some parts sectioned; and Fig. 4. is a section taken on the line00* m on Fig. 3.

The rake proper comprises an ordinary toothed rake bar 1, that issuitably connected to an ordinary handle or pole 2, but as shown, isconnected thereto by bars 3 that radiate from the end of the pole andare rigidly attached to the ends of the said rake bar. As a convenientmeans for application of the scraper attachment to the rake, flat bars4: are secured to the rake bar 1 and to the diverging .bars 3. The blade5 of the Specification of Letters Patent.

wings of the said hinges are adjustably connected to the upper edge ofthe said scraper blade by slot and bolt connections 9. The slot and boltconnections 9 permit vertical adjustments of the lower edge of thescraper blade, while the slot and bolt connections 8 permit forward andrearward adjustments of the hinge pivots 7 in respect to the toothedrake bar 1. Preferably, the for ward movement of the scraper blade islimited by stop devices in the-form of resilient spring arms 10 that areadjustably connected to the rake head by the bolts 8 which pass alsothrough slots therein. I

The scraper blade is put under yielding strain to move forward by acoiled spring 11, the rear end of which, as shown, is connected to aneye12 on the intermediate portion of the said scraper blade, and the frontend of which is connected by a link or wire 13 to an anchoring hook oreye 14: on the handle 2.

Ground engaging shoes 15 preferably having serrated or toothed loweredges, are rigidly secured to the end portions of the scraper bladeandare provided with rearwardly extended arms 16 having laterallyprojecting lugs through which adjustable stop screws 17 are arranged towork. Said stop screws 17 are preferably held in their set adjustmentsby jam nuts 18, and their inner ends are adapted to engage the end teethof the toothed bar 1 to limit the forward movement of the scraper blade.The stop arms 10 are resilient or yielding, so that the blade, afterengaging the same, may move still slightly farther forward until thefront ends of the stop screws 18 engage the rake teeth. When desired,however, either one of the said stop devices 10 or 18 may be usedindependently of the other.

The scraper blade 5 is provided with a toothed or comb-like cleaning bar19 that works between the teeth of the rake, and under the forwardswinging movements of the scraper blade 5, forces downward on the raketeeth, any grass or leaves which may have stuck between the same.Furthermore, the said so-called cleaning blade 19 affords a stop forpreventing grass and leaves from Working their way between the raketeeth, upward beyond the same.

The operation of the combined rake and scraper is substantially asfollows: Vhen the rake is drawn forward, the engagement of the dependinglower edge of the scraper blade 5, assisted by the engagement of theshoes 15- with the ground, will cause the said scraper blade to moverearward against the rake teeth or into a position shown in Fig. 1; andwhen the rake is then drawn forward, all acorns, leaves or likearticles, which would otherwise pass between the rake teeth, will bescraped forward. Then when the pressure on the scraper blade is relievedat the limit of the forward movement of the rake, the spring 11 willquickly throw the scraper blade forward against the resilient stops 10.This statement, of course, assumes that the set screws 18 are set topermit the above noted engagement between the scraper blade and the saidstop stem. The quick forward movement given to the scraper blade by thespring 11 causes the scraper blade to kick or propel forward the acorns,leaves, or other articles scraped up by the same, under forward movementof the rake; and furthermore, the resilient stops 10 will cause thescraper blade to stop with a trembling action which has the efiect ofcleaning the same of the articles scraped up thereby. The closeness withwhich the lower edge of the scraper blade and the lower ends of the raketeeth will engage with the ground may be regulated,by raising orlowering the front end of the handle 2. F or example, downward movementof the front end of the handle will have the effect of lowering thelower edge of the scraper blade and raising the lower ends of the raketeeth, while raising of the front end of the said handle will have areverse action, towit, will raise the lower edge of the scraper bladeand lower the lower ends of the rake teeth.

In actual practice, the efiiciency of the combined rake and scraperabove described has been thoroughly demonstrated.

What I claim is:

1. The combination with a rake, of a scraper blade mounted for swingingmovements in front thereof, having a ground engaging edge and providedwith a portion having open notches in which the teeth of said rakenormally lie, with the portions between notches projecting between thesaid teeth.

2. The combination with a, rake, of a scraper blade mounted for swingingmovements in front of the rake teeth, and yielding means tending to movesaid scraper blade forward; said scraper blade being verticallyadjustable.

3. The combination with a rake, of a scraper blade mounted for swingingmove ments in front of the rake teeth, and yielding means tending tomove said scraper blade forward, said scraper blade being vertically andforwardly and rearwardly adjustable.

4;. The combination with a rake, of a scraper blade mounted for swingingmovements in front of the rake teeth, and yielding means tending to movesaid scraper blade. forward, said scraper blade having a toothed barprojecting rearward between the teeth of the rake.

5. The combination with a rake, of a scraper blade mounted for swingingmovements in front of the rake teeth, and yielding means tending to movesaid scraper blade forward, said blade having ground engaging teeth atits ends. A

6. The combination with a rake, of a scraper blade mounted for swingingmovements in front of the rake teeth, and yielding means tending to movesaid scraper blade forward, and a stop carried by said scraper blade andengageable with the teeth of the rake. I

7. The combination with a rake, of a scraper blade mounted for swingingmovements in front of the rake teeth, and yielding means tending to movesaid scraper blade forward, and a resilient blade stop on the rake headlimiting the forward movement of the scraper blade.

8. The combination with a rake, of a scraper blade mounted for swingingmovements in front of the rake teeth, and yielding means tending to movesaid scraper blade forward, the said scraper blade having a notchedlower edge.

In testimony whereof I affix my signa' ture in presence of twowitnesses.
